Understanding Cost Per Acquisition

What is CPA?

Cost Per Acquisition (CPA) measures the total cost to acquire one paying customer through your advertising campaigns. It includes all ad spend divided by the number of conversions. For example, if you spend ₹10,000 and get 20 sales, your CPA is ₹500. This metric is critical for determining campaign profitability and scalability.

How to Calculate CPA

CPA = Total Ad Spend / Number of Conversions

Example: You spent ₹25,000 on Google Ads this month and received 50 orders. Your CPA is ₹25,000 ÷ 50 = ₹500 per customer.

CPA vs Customer Lifetime Value

The golden rule: Your CPA must be lower than your Customer Lifetime Value (LTV). If your average customer is worth ₹2,000 over their lifetime and your CPA is ₹500, you have a healthy 4:1 LTV:CPA ratio, which is considered excellent for most businesses.

How to Lower Your CPA

  • Improve landing page conversion rate: Better pages = more conversions = lower CPA
  • Target high-intent keywords: Focus on keywords closer to purchase intent
  • Use remarketing campaigns: Target warm audiences who already know your brand
  • Optimize ad scheduling: Run ads during your highest-converting hours
  • Refine audience targeting: Exclude non-converting demographics
